" This-invention relates to chucks and more machines for holding and rotating the coil beingwound. I I II II An object of this invention is to provide a chuck of the type set forth constructed and arranged to permit ready removal of a finished coil therefr'om.' I I A further object is to provide an'improved construction of coil holding chuck which can be readily collapsedto release a finished coil or expanded to operative position without requiring the use of any tools. I I 1 These andother objects which will be apparent to those skilled in this particular art are .accomplished bymeans of the invention illustrated in the accompanying drawings n which I I Fig. 1 is a viewin elevation'of a coil winding chuck constructed in accordance with one embodiment of this invention.

The particular embodiment of this invention. which has been'chosen for thepurposes of illustration comprises a collapsible type of coil supporting chuck which can'be readily collapsed to free a finished coil therefrom, or

expanded to operative coil winding position,

without requiring the use of any extraneous tools. The arrangement is such thatasingle operating lever is employed for placing the Fig. 5 is a View similar to 1 showing chuck parts either in operative coilsupporty ing-position or in inoperativecollap'sed position. The chuck includes a pair'of face plates, one of which is readily removable to permitremoval of the finished coil. Alocking means for the removable face plate is so arranged that the single operating lever operates the lock for securing 'the face plate. in

position when the chuckis expanded or for unlocking the face plate to permit its removal when the chuck is collapsed. I I

' As 'illustrated,itheinvention is shown in connection with a coil winding machine 15 having a chuck supporting, rotary, coilwi nding spindle 16' formed with projecting threaded end 17 upon which is mounted a sleeve 18p A chuck supporting stud shaft 19 has its inner end secured 'within and supported by the sleeve 18. i I I coil supporting core 20, see Figs. 3, 4: and 7, is illustratedas being rectangular in shape, but it will beapparent that any desired figuration'of corecan be employed,- depending uponthe'form of coil being wound. 'Asillus trated, the core includesan expander 21 slidably mounted o-n the stud shaft 19 and hav ing inclined upper and lowerfac'es 22' and 28, respectively." Expansible coil supporting upper and'lo'wercore blocks "243'an'd 25, re-

spectively, see Figs. 3' and'-' 7,*are' slidably mounted on the inclined faces,'by suitable dovetail joints, so asto be contracted and expanded by movement-ofthecore member I 21 longitudinally of the supporting shaft'19. An inner face plate 26 has a hub 27 -slidably mounted uponthe movable core member 21 and having an outwardly extending annular portion" 28 formingth'e inner face plate '26 toggle links29 with the sleeve 18. J Achuck of the chuck. The hub .27 isconnecte'd by In operating collar30 is slidablyi mounted on the sleeve 18 and movable longitudinally thereof by a collar operating handle 31. pivoted to a handle supporting bracket .32 mounted on the machine. The handleisprovided with collar.

engaging rollers 33 secured to the handle and positioned within an annular slot 34: formed on the outer surface ofthe collar to permit the same to be movedlongitudinally ofthe sleeve 18 by the handle 31.. The chuck operating collar 30 causes the ends of the slots 35 rating sleeve is provided with diametrically opposed slots35 in which are positioned the outwardly curved ends 36 of the associated toggle lever 37, and toggle locking screws 38 extend through the collar for locking the toggle against movement when the chuck is in operative position. It will be apparent that in operative position, as illustrated in.

Fig. 4, the enlarged inner end of the toggle locking screws 38 hold the-toggles 29' so as to prevent any'movement of the faceplate 26,

but that inward movement of the chuck operto strike the curved 'ends 36 of the ltoggle operating levers'37 and'at the same time shift the. toggle locking screws 38 so as to permit the toggles to break and move the face plate 2.6- sufiiciently to free it fromthe pressure of a finished coil.,-

The longitudinally movable core member 21 is also connected tothe chuck operating collar 30 by means of pins 39 which extend outwardly through the slots 40 formed in the l1ub27, see Figs. 3 and 6, and areconnected by links 41 to the adjacent end of the col1ar-30.

The outer face plater42 of the chuck is formed by .a block 43 having-an eccentrically positioned rectangular shaft receiving opening 44, see Fig. 3, which permits-theblock to: be placed on the shaft .19 and. removed therefrom in a: manner somewhat similar .to the well-knownbayonet lock.: The outer-end of the s1idable-core'member'21 is-provided witha locking pin 45which engagesa pin reeeivingopening46in the block 43 when the chuck. members are in expanded, operative position, thus locking the block43 in position on-theshaft betweenthe coreblocks 24 and. varr-outer nut 4'7. which is pinned tov the shaft by a pin 48, seeFigs.-1 and 5. As-shownin Fig; 2, thenut 47 is of rectangular outline corresponding to the opening 44 in theblock 43, and it will be apparent that-when the chuck is collapsed and thepin 45 withdrawn fr'omithe block 43, the latter can'be raised until the opening 44 is in-line with thenut 47 when the entire-block or face plate canbe removed fromthe spindle.

' As. shown-in Fig. 7,the coremembers 24 are provided with threaded wiredirecting and coil supportingtcoriiervpieces 49. The sleeve 30'is'provided'witha handwheel 50 to permit manualrotation of the chuck in starting the first: layer of the coilL' a In yoperation, assuming that the parts are in J the expanded coil s upporting position- 'ila Iustra-ted in Figs. 3 and 4,a 'coil will be wound around the core between face plates 26 and 42 in the usual manner. When the coil iscompleted the strands are quite tightly wound around the core and bear against the opposite faceplates with moreor less, pressure. Mere- 1y by shifting the single operating handle 31 to the left to substantially the position indicated in Fig. 5 causes the slidable core member 21 to move longitudinally of the core members 24 and 25, collapsing the core by drawing the members inwardly toward the shaft 19 and freeing the coil from the core. As the collar 30 approaches the end of its movement, theends of the slots 35 engage the curved ends .36of toggle levers 37 to break the toggles 29 and shift the face plate 26 a dis tance sufficient to free the strands of the coil 3 from the-pressure thereof. Simultaneously,

the locking pin 45 is retracted from the face block 43 so that the latter can-be lifted off in the manner above described and the finished coil removed from the chuck. To place the parts in their operating position again, the face. block43 is replaced, after which the handle .31 is moved-so as to return the parts totheir expanded operative position in which the core member 21 is shifted so as to move the parts 24 and 25 .to..their expanded position and to position theflocking pin 45 in the locking slot .46 of the face plate. At the same time, the inner'ends of the toggle lockingscrews 38 have been moved so as to lock the, toggles29 in operativeposition;

The facerplates are provided with suitable slots 51which may beemployed to hold cords or tapes for binding the completed coil before releasing inorder to avoid collapse, and also. to receive the projecting inner end of the winding wire. This latter serves to. lock changes, additions, omissions and substitutions can be made therein without departing fromthe spirit of. this invention or the scope of the appended --claims.'

WhatI claim as new and desire to secure.
